Feline bordetellosis is a contagious respiratory infection caused by the bacterium Bordetella bronchiseptica. While this bacterium may be the primary cause of the disease, it can also be secondary (related) to various viral infections. Cats of all ages may contract this disease, although it typically occurs in younger cats.

Feline upper airway infections, sometimes called upper respiratory infections, are very common. They resemble the common cold in people and are characterized by clinical signs such as sneezing, wheezing, and discharge from the eyes and nose. Along with the rhinotracheitis virus, feline calicivirus (FCV) is responsible for most feline upper respiratory infections.

Feline chlamydiosis (also called feline pneumonitis) is caused by the bacterial organism Chlamydophila felis (C. felis). The C. felis organism does not live for very long in the environment, so infection is generally spread through direct or close contact with a sick cat. Because infected cats sometimes sneeze, contact with these droplets can also spread the infection.

Feline distemper is the common name for the feline panleukopenia virus (FPV), also called feline parvovirus. Despite the name feline distemper, this contagious disease does not affect a cat’s temperament. Rather, FPV causes serious disease in infected cats and can be fatal.

Feline leukemia virus (FeLV) is also contagious among cats. Unlike many other viruses that enter specific cells in the body and destroy them, FeLV enters certain cells in a cat’s body and changes the cells’ genetic characteristics. This permits FeLV to continue reproducing within the cat each time infected cells divide. This allows FeLV to become dormant (inactive) in some cats, making disease transmission and prognosis (outlook) difficult to predict.

Feline distemper is the common name for the feline panleukopenia virus (FPV), which is sometimes called feline parvovirus. Despite the name feline distemper virus, infection with this virus does not affect a cat’s temperament. Rather, FPV causes serious disease in infected cats and can be fatal.

Rabies is a dangerous virus that infects animals and humans worldwide. The virus is generally fatal in all species, and any warmblooded animal can become infected. Foxes, skunks, coyotes, and certain rodents are implicated in many cases of exposure. Surprisingly, cats are more commonly involved in transmission of rabies than dogs. In fact, cats are the number-one domestic animal carrier of rabies in the United States.
